BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a mobile terminal and in particular, to a mobile terminal which is bearable by each user and which can perform receiving and sending operations of information, such as speech or data.

2. Description of the Related Art

Recently, a mobile terminal has been quickly spread worldwide with an outstanding development of a technology and an increase of functions of the mobile terminal. Specifically, such development is led by remarkable progress of communication technology and an IC (Integrated Circuit) technology.

For example, a mobile telephone can be used not only to communicate with domestic people but also to make an international phone call.

Nowadays, using the mobile terminal including a mobile telephone, mobile PC, and others, wherever a user of the mobile terminal goes to or whenever the user uses the mobile terminal, the user can communicates with someone.

Because of improvement of the communication technology and the IC technology, we can receive a great convenience.

In this specification, the mobile terminal is regarded as including all portable terminals which can perform radio communication and display characters, animated images, and still image. Further, the mobile terminal includes a terminal which can output a sound. Also, as described above, the mobile terminal includes a mobile telephone, a mobile PC, a PDA (Personal Digital Assistant), and other portable computers.

However, all users (persons) of the mobile terminal do not always use the same language. If a user of the mobile terminal can not understand a language of another user who intends to communicate with the user (that is, if there is a language barrier between them), they can not understand each other and, as a result, smooth communication or conversation is impossible between them.

Recently, English tends to be used as a common language among people living in different countries. But, it is needless to say that communication among a variety of languages becomes indispensable without relying on English alone. Under the circumstances, even if persons in many areas or many countries can be connected to each other through conventional mobile terminals, it is almost impossible to communicate or understand each other in the true sense of the words.

In Japanese Unexamined Patent Publication (JP-A) No. Hei 11-243571, namely, 243571/1999, proposal has been made about a pager receiver that has a function of translating a message written in one language and received from a transmission station, into another language understood by a bearer. Herein, it is to be noted that such a pager receiver can not send or transmit any message, speech, or data. Therefore, no consideration has been made about a mobile terminal which can sends or transmit any message or data to any other subscriber or station.

 DESCRIPTION OF THE PREFERRED EMBODIMENT

According to the invention, an automatic translation (language translation) function is added to a mobile terminal to solve the above described problems. Further, in the invention, the mobile terminal automatically performs, during communication, language translation which is adapted to a user or which is selected by the user by incorporating at least one of functions as follows.

(1) Function for storing a language of the user in the form of a “country (language) ID” into the mobile terminal.

(2) Function for determining a language used in a place where the user is present by using a country ID included in broadcast information from a base station related to the mobile terminal.

As known in the art, each base station radiates the broadcast information within a zone surrounding the base station. In addition, broadcast information includes a variety of data used to communicate between the base station and mobile terminals in the zone. The mobile terminals receive the information through a channel and call (or telephone) or wait on the basis of the data in the broadcast information. In the broadcast information, the country code used in the invention may be included.

(3) Function for determining a language of the other user talking to the user, by using a country ID included in a telephone number sent from the other user prior to communication. When the user calls using the mobile terminal, the mobile terminal determines a language of the other user from a country ID included in a calling telephone number. On the other hand, when the other user calls the user, the mobile terminal of the user determines a language of the other user from a country ID included in a caller telephone number received from the other user's side.

(4) Function for informing the other user of a country ID stored in a mobile terminal of the other user via a control signal.

(5) Function for recognizing a country ID stored in a mobile terminal of the other user by receiving a control signal form the mobile terminal of the other user prior to communication.

By using a current sophisticated IC technology, these functions can be realized in an extremely compact size and at comparatively low costs.

Next, a mobile terminal illustrated in FIG. 1 has an automatic translation function according to an embodiment of the invention, together with sending and receiving functions. Specifically, the mobile terminal includes a sending user I/F (interface) unit 1, a receiving user I/F (interface) unit 2, a language translation unit 3, a control unit 4, a sending baseband processing unit 5 (hereinafter, “baseband” is abbreviated to “BB”), a receiving BB processing unit 6, a radio unit 7, and an antenna 8.

The sending user I/F unit 1 may includes a microphone or keyboard used to enter user information and control information. The receiving user I/F unit 2 may include a speaker or a monitor used to output the user information and control information to the user.

The language translation unit 3 performs language translation (will be simply called “translation” hereinafter) on the user information entered from the sending user I/F unit 1 or output to the receiving user I/F unit 2, in response to the control unit 4.

The control unit 4 selects a language translation pattern adapted to the user and informs the language translation unit 3 of the pattern. Such selection of the pattern in the control unit 4 is carried out on the basis of user settings entered from the sending user I/F unit 1, broadcast information from the receiving BB processing unit 6, and a calling or originator's telephone number from the sending user I/F unit 1 or the receiving BB processing unit 6.

The language translation unit 3 includes, in general, sets of a dictionary and a translation engine. And each of the sets corresponds to a translation pattern.

The mobile terminal also includes a memory (not shown) storing the user settings, notification information, and the calling telephone number. The notification information is used for notification of a cell or an area in which the mobile terminal is present. Further, the mobile terminal generates a control signal other than the user information, and processes a received control signal.

The sending BB processing unit 5 performs a baseband process on the user information and the control information both of which are to be sent. The receiving BB processing unit 6 performs baseband process on the user information and the control information which are received. The radio unit 7 and the antenna 8 perform sending/receiving via a radio network.

Next, description is made about operations of the mobile terminal of the invention with reference to FIGS. 2 through 5.

FIG. 2A shows a calling or sending process. At step A1, a user of the mobile terminal enters or inputs a calling telephone number (a telephone number of a subscriber to be called by the user) via an input device, such as the microphone or the keyboard, by sometime referring to a telephone directory.

Herein, it is assumed that the called subscriber uses a telephone or computer located in a home and the telephone and the computer can communicates through a fixed network connected to the home.

After that, calling operation is started in the mobile terminal of the user (step A2). Then, the mobile terminal selects a language translation pattern by comparing a language stored in the own mobile terminal, with a country ID included in the calling telephone number (step A3).

Next, communication process is started (step A4). Finally, in the communication process, data which are received or to be sent are properly and smoothly translated by using the selected language translation pattern (step A5).

FIG. 2B shows a process of receiving message. At first, the mobile terminal starts receiving messages (step B1). Then, the mobile terminal recognizes a telephone number of a subscriber (originator) who calls the user of the mobile terminal (step B2). Such a telephone number of a calling subscriber can be recognized by the use of an originator number notification service, namely, a calling line identification presentation service. Herein, the originator number notification service is generally provided by a telephone company.

Herein, it is also assumed that the calling people uses a telephone or computer located in a home and the telephone or computer communicates through a fixed network connected to the home.

Then, the mobile terminal selects a language translation pattern by comparing the above language stored in the own mobile terminal with a country ID included in the telephone number obtained at the step B2 (step B3). Next, communication process is started (step B4). Finally, in the communication process, data which are received or to be sent are properly and smoothly translated into the selected language by using the selected language translation pattern (step B5).

Next, description is made about operations executed when the mobile terminal of the invention calls to a domestic fixed network, with reference to FIG. 3.

At first, a user of the mobile terminal enters a calling telephone number (a telephone number of a subscriber to be called by the user) via an input device, such as the microphone or the keyboard (step C1).

Herein, it is assumed that the called subscriber uses a telephone or computer located in a home and the telephone or the computer communicates through a fixed network connected to the home.

In this event, since domestic communication, that is, no international communication with a foreign country is carried out, a country code (namely, a country ID) of the telephone number is not required.

Therefore, the mobile terminal specifies a country ID by fetching a country ID included in broadcast information from a base station related to the mobile terminal (step C2).

Thereafter, calling operation is started (step C3). Then, the mobile terminal selects a language translation pattern by comparing a language which is used and stored in the own mobile terminal with the country ID specified in step C2 (step C4). Next, communication process is started (step C5).

During the communication between the user of the mobile terminal and the called people using non-mobile terminal, the mobile terminal receives and sends languages by properly and smoothly translating them by using the selected language translation pattern (step C6).

Next, description is made with reference to FIG. 4 about operations performed when the mobile terminal of the invention receives a call from a domestic fixed network.

At first, the mobile terminal starts receiving messages (step D1). Then, the mobile terminal recognizes a telephone number of a subscriber (originator) who calls the user of the mobile terminal (step D2), using an originator number notification.

Herein, it is assumed that the calling people uses a telephone or computer located in a home communicating through a fixed network to the home.

But, since it is a domestic communication, a country code (a country ID) of the telephone number is included in the telephone number obtained from the originator number notification.

Therefore, the mobile terminal specifies a country ID by specifying a place where the user of the mobile terminal and the calling people are present, from a country ID included in broadcast information from a base station related to the mobile terminal (step D3).

Then, the mobile terminal selects a language translation pattern by comparing the above language which is used and stored in the own mobile terminal with a country ID included in the telephone number obtained in step D3 (step D4). Next, communication process is started (step D5).

Finally, in the communication between the user of the mobile terminal and the calling people using non-mobile terminal, at the mobile terminal, languages which are received or to be sent are properly and smoothly translated by using the selected language translation pattern (step D6).

Next, description is made about operations when a communication is made between mobile terminals with reference to FIG. 5.

If a communication is made between two mobile terminals, at least one of the mobile terminals should know a language of the other mobile terminal. Therefore, language translation is performed as shown in FIG. 5. Also, the one mobile terminal is required to communicate a control signal to inform the other mobile terminal of a language used in the one mobile terminal, and a network between them should support this function.

At first, calling user enters a calling telephone number (a telephone number of an object to be called by the calling user) via an input device such as the microphone or the keyboard (step E1).

In this case, since the called terminal is a mobile terminal (a mobile telephone), a country code (a country ID) is not included in the telephone number.

After that, calling operation is started (step E2). Then, the receiving mobile terminal starts a receiving operation (step E3). Further, call connection is established (step E4).

Next, the calling mobile terminal sends a language of own terminal in the form of the control signal to the receiving mobile terminal (step E5). And the receiving mobile terminal receives the control signal and recognizes the language used in the calling mobile terminal (step E6).

Then, the receiving mobile terminal selects a language translation pattern by comparing a language which is used and stored in the own mobile terminal with the language recognized at step E6 (step E7).

Next, communication process is started (step E8). Finally, in the communication process, languages which are received or to be sent are properly and smoothly translated by using the selected language translation pattern (step E9).

Also, about steps E5 to E9, the operations in the receiving mobile terminal may be changed to the operations in the calling mobile terminal.

Further, the method of the invention can be applied to a mobile terminal which can perform communication via a radio network as described above, but the method also can be applied to a communication between terminals each of which is connected to a fixed network such as a telephone settled in a home.

Still further, a program to perform the method of the invention can be provided via a recording medium. A mobile terminal can includes a CPU, a memory, and a recording medium drive. Instructions of the program are loaded into the memory of the mobile terminal via the recording medium driver. And then, according to the instructions, the CPU controls and manages elements of the mobile terminal to execute the method of the invention.

Instead of the recording medium, the instructions may be loaded to the memory via a radio network or other routes.

As described above, description has been made about a configuration and operations of the mobile terminal according to a preferred embodiment of the invention. However, the embodiment of the invention is merely illustrated and it is noted that the scope of the invention should not be limited to the embodiment. It is easily understood for the skilled people in the art that a variety of amendments and modification may be taken for the mobile terminal according to a specific application within the scope of the spirit of the invention.
